Specific embodiment
In the following description, various aspects of the invention will be described.For explanation, state specific in detail enough Configuration and details, to provide the comprehensive understanding to the application.It will be apparent however, to one skilled in the art that it is apparent that can be The theme of the application is put into practice in the case of there is no detail as herein described.
With reference first to Fig. 1 to 6, the cutting insert 10 according to the application is it illustrates.Cutting insert 10 is intended to for milling Operation and can be by the firm of the such as hard alloy obtained by molding compacting and the carbide powder in vitrified bonding agent And anti abrasive material is made.
Cutting insert 10 has two relative identical end surfaces 12 and the outer surface extended between end surfaces 12 14.In the case where having no loss of generality, end surfaces 12 may be considered that the upper end face 12 ' and rear surface for constituting cutting insert 12’’.Cutting insert 10 is foursquare in its end-view.Periphery side surface 14 includes four identical side surfaces 16 and four Individual identical outer corner surface 18, adjacent side surface 16 converges at the outer corner surface.It is such as visible from Fig. 5 and 6, in cutting In the side view of empiecement 10, side surface 16 is parallelogram shape.Cutting insert 10 has central axis A and in end surfaces The through hole 20 extended between 12.The through hole can be centered on central axis A.
Cutting insert 10 has between end surfaces 12 and through mid-plane M of outer surface 14.Mid-plane M can With perpendicular to outer surface 14.Mid-plane M can be perpendicular to central axis A.
Each end surfaces 12 is with the diagonally relative recessed corner 22 ' of four corners 22, i.e., two and two along right The relative convex corner 22 ' of linea angulata '.Recessed corner 22 ' is than convex corner 22 ' ' closer to mid-plane M.Each outer corner surface 18 one in two relative end surfaces 12（For example, upper end face 12 '）Given convex corner 20 ' ' it is relative with two End surfaces 12 in another（For example, rear surface 12 ' '）Given recessed corner 20 ' between extend.Diagonal L is passed through The recessed corner 20 ' of each end surfaces 12.In other words, diagonal is related to each end surfaces.Each end surfaces 12 is from convex turn Angle 22 ' ' incline to the diagonal L related to end surfaces 12.In the end-view of cutting insert 10, central axis A passes through two The intersection point of diagonal L, it should be appreciated that non-intersect in three dimensions to two related diagonal Ls of end surfaces 12 ', 12 ' '.
Periphery cutting edge 24 is formed at the cross-shaped portion of each end surfaces 12 and outer surface 14.For each end surfaces 12, periphery cutting edge 24 includes four main cutting edges 26 for being intersected and being formed with end surfaces 12 by side surface 16, and passes through Four corner cutting edges 28 that outer corner surface 18 intersects and formed with end surfaces 12.Therefore, cutting insert 10 is by means of total eight Individual main cutting edge 26 and eight corner cutting edges 28 and it is indexable.Each main cutting edge 26 prolongs between a pair of corner cutting edges 28 Stretch.A corner cutting edge 28 being connected in this corner cutting edge 28 of each pair of common main cutting edge 26 is located at recessed turn The place of angle 22 ', and another corner cutting edge 28 of the centering is located at convex corner 22 ' ' place.In each end surfaces 12, tiltedly Face 30 extends from periphery cutting edge 24, and the chip being removed from workpiece during metal cutting operation flows along the inclined-plane 30.
Fig. 3 and 4 illustrates for the given orientation of cutting insert 10 the diagonally view of L.As described previously for figure The orientation of the cutting insert 10 shown in 1 a, end surfaces 12 will be referred to as upper end face 12 ', and another end surfaces 12 will be by Referred to as rear surface 12 ' '.Fig. 3 illustrates the view along the diagonal L related to upper end face 12 ', in referred to herein as cutting edge First corner view of piece.In the first corner view, outer surface 14 has the V-arrangement shape for facing upwards.Fig. 4 is illustrated along with End surfaces 12 ' ' related diagonal L view, in the second corner view of referred to herein as cutting insert.In the second rotation angle visual In figure, outer surface 14 has prone V-arrangement shape.Second corner view revolves relative to the first side view around central axis A Turn 90 °.From above it should be understood that cutting insert can have 180 ° of rotational symmetries with regard to central axis A.Two views are all Obtain for the orientation of the cutting insert 10 shown in Fig. 1.As figure is visible from Fig. 3 and 4, outer surface 14 is diagonally L's There is V-arrangement shape in view.In figures 3 and 4 seen V-arrangement shape is identical in form, but " V " is fixed in opposite direction To.
Referring now to Fig. 7 and 8, it illustrates the milling tool 32 of the concrete application according to subject matter.Milling tool 32 With rotation axiss R and multiple empiecement notches 34, cutting insert 10 is mounted and fixed in empiecement notch 34 by screw 36. Each empiecement notch 34 includes the diapire 38 adjacent with side wall 40.Side wall 40 is provided with the given side surface 16 with cutting insert 10 The side abutment surface 42 that adjacent two separate.Diapire 38 is provided with and is adjoined with the non-operational end surfaces 12 of cutting insert 10 Two non-coplanar bottom abutment surfaces 44.
Cutting insert 10 can be installed such that them and be differently directed with two of operability main cutting edge 26 and be replaced Place on ground.Some cutting inserts 10 ' are oriented makes its operability main cutting edge 26 ' with positive axial inclination（Also scheme in Figure 5 Show）, and other cutting inserts 10 ' ' be oriented make its operability main cutting edge 26 ' ' have negative axial inclination（Also in Fig. 6 Middle diagram）.
Therefore, have and can be operated with positive axial inclination according to each end surfaces 12 of the cutting insert 10 of subject matter Two main cutting edges 26 and can with bear axial inclination operation two main cutting edges.Therefore, cutting insert 10 is amounted to and had Four main cutting edges 26 that can be operated with positive axial inclination and four main cutting edges that can be operated with negative axial inclination.
When both positive axial inclination and negative axial inclination is needed, substantially had according to the cutting insert 10 of subject matter Profit.Single cutting insert 10 may be used to provide the cutting edge with both positive axial inclination and negative axial inclination, every kind of to cut Cut sword and amount to four.
Although describing the present invention with certain exact level, it should be understood that, without departing substantially from hereafter requiring Various modifications may be made in the case of the scope of the present invention of protection and improves.
